RESUMO
<p><b>OBJECTIVES</b>To study whether Chinese Medicine Yiqihuoxuetang(YQHXT) could inhibit antisperm antibodies in infertile men, and to explore the therapeutical mechanism of YQHXT.</p><p><b>METHODS</b>Thirty infertile men with antisperm antibodies took YQHXT continuously for 60 days. Indirect immuno-fluorescence technique (IFT) was used to detect the levels of CD3, CD4, CD8 and CD4/CD8 ratio before and after treatment.</p><p><b>RESULTS</b>CD4 value and CD4/CD8 ratio after treatment were significantly lower than before treatment (P < 0.05); CD8 value became significantly higher(P < 0.05).</p><p><b>CONCLUSIONS</b>The results indicated that YQHXT could inhibit antisperm antibodies by keeping the balance of T-lymphocyte subpopulation in immunoinfertile men.</p>
